Most larger companies are making it between difficult and impossible to print documents. One company I visited had a wall of shame for people who printed the most pages in the previous month - it was one page of a scrolling PowerPoint on a video display in the lobby (the next page said. "Welcome our visitor, GopherT". Everything is saved to cloud drives as pdf and most employees have two or more big monitors or crystal clear iPads to read documents.
I've been in specialty chemical sales and marketing for 30 years and paper mills use all kinds of additives. Each type of paper product needs specific materials. I would love to see evidence to the contrary but office paper (copy paper/laser printing paper) demand reached its peak in 2005 at 6M tons and down to 5M by 2010 and under 3M now. The toner/inkjet companies were hurt more than the paper industry by the decline.
